Hercules SLR Lever Hoist Service: Inspection, Test, Maintenance, And Certification

Hoist inspection: According to ASME standard B30.16, manual, electric, and air hoists need to be inspected by a trained professional at least once a year.
The consequences of incorrect maintenance and inspections can be life or death. Not to mention the immense financial impact an accident can have on a business.
The hoist safety experts at Hercules SLR can thoroughly inspect, test, and certify lifting hoists. Bring them to one of our shops across the country or have our trained service professionals come to you.
Our inspectors check over 25 inspection points on every hoist, ensuring they undergo a rigorous and thorough examination prior to designating them as “safe”.

Frequently Asked Questions

  • Normal Service—yearly

  • All inspections shall be performed by a designated person per the manufacturer’s recommendations and with the requirements of ASME B30.21. Any deficiencies identified shall be examined and a determination made by a qualified person as to whether they constitute hazards and whether a more detailed inspection or disassembly is required.

  • Excessive component wear, cracks, distortion, warping, or other internal damage — or any other part that displays indications of potential failure — will be noted by the inspector. Based on that assessment, the hoist may be deemed beyond reasonable repair, and replacement is recommended.

What should you do before you use a hoist?

If you’re a rigger, or have worked in construction, you’ve likely used some sort of hoist before. Hoists are mechanical devices use to lift, pull and hoist, and are equipped with a pulley. They’ve also been around for awhile—historians haven’t been able to pinpoint exactly when the first hoist was used, but even Leonardo da Vinci had a hoist design.

Since then, hoist technology has come a long way – hoists are available in manual, electric, hydraulic and even universal styles. They’re used in a number of different industries. Today, we cover more about hoists used for securing, lifting and rigging applications and what exactly you should do before you use one.


We talk a lot about hazards, how to avoid them and prevent them on a job site. There are a number of hazards that present themselves at work – both chemical and physical. When rigging with hoists, there are a number of hazards there.

Some of the most common hazards are:

  • Falling equipment, materials, etc.
  • Electrical issues
  • Loading hoist beyond it’s WLL or SLL, known as overloading


It’s important that anyone using the hoist, or operating rigging equipment in general, has proper training in hoist safety and operating procedures. Hoists are often used in rigging, and are commonly-known as a component for cranes. Hercules’ highly-skilled trainers teach a variety of courses that will prepare you to rig with hoists.
